I thought most of them were gone, except the ones dealing with Ulduar among other things, and the Red Dragonflight took over management duties?

Except that temperatures on Titan are significantly lower than they are on Earth. Life based on liquid water is unlikely to exist there.

Interesting writing - "on the Caribbean island of Trinidad and Tobago."

That's two islands. A lake can't be on both. Which island is it on?

I dunno about the fundies, but I'm sure the GOP is scrambling to figure out why they are against it.

That's neat and all, but "possible that there's life there" != "there is life there." Still cool, though.

The GOP is fine with that discovery as long as those organisms can be used as an alternative fuel source.

Interesting article, though I don't think a direct comparison to Titan can be made. Big differences I see are:

1) Different temperatures (as pointed out above), however, subsurface temperatures may be higher due to gravitational stresses.

2) Hydrocarbons on Titan are much simpler (methane, ethane, etc.) than ones on Earth, (octane and above, aromatics, PAHs, etc.)

3) Mineral composition of Earth and Titan are most likely different (someone can correct me on this one, I'm just guessing)

Either way still, it gives a much larger range of environments that could support life, very cool!

Nice to see that hydrocarbon lakes have a helpful spirit

"Pitch lake, they say, is teaming with microbial life"

The Icelander: Life based on liquid water is unlikely to exist there.

You never know. As Reverend J pointed out, if you go down a few meters, the temperatures might be higher. Also, the hydrocarbons may prevent the ice from crystallizing.

The Icelander: Life based on liquid water is unlikely to exist there.

While water is a very good solvent, there's plenty of other possible solvents at those temperatures. I'd be much more concerned about there being enough energy in the environment to have any kind of metabolism at all.

The pace of life on Titan would likely be very slow.

Reverend J: Hydrocarbons on Titan are much simpler

Mmm, not as simple as you're thinking. They can get as far along as benzane thanks to solar ultraviolet. The tholins is similar to what likely gave Earth its initial richness in organics.

Contrabulous Flabtraption: Call me when we actually do something.

We actually discovered an organism that lives in hydrocarbon lakes without water and has a metal-based metabolism.

Which is farking awesome.

Wouldn't common sense dictate that there is OBVIOUSLY life on other planets?

SacriliciousBeerSwiller: Wouldn't common sense dictate that there is OBVIOUSLY life on other planets?

Yes, but which ones? If life exists in a different galaxy, that's not terribly interesting, because we'll never be able to investigate it. But if life exists in our solar system- now that opens up an interesting opportunity for xenobiology.

The Drake equation.

This equation was devised by Frank Drake in 1961, in an attempt to estimate the number of extraterrestrial civilizations in the Milky Way with which we might come into contact.

i thought the Drake equation was create to estimate the number of intellegent species not bacteria.. i could be wrong tho

"...respiring with metals", don't we do that with blood?, or are they breathing out a gas with metals in it....

Keep in mind, lots of places can support life. That doesn't mean that life can get started there.

You are right.

You can, however, only follow the equation until the point of just having life and It makes a point all the same.

Don't mean to nitpick to much, but by "benzane" do you mean benzene or benzyne? I ask because those two would have different chemical pathways if they exist in Titan's atmosphere.

As a side note I hate the name "tholins" because it sounds like "thiol" which means "sulfur containing" and also like "analine", and the term means neither of them.

/Love Carl, but leave the chemical naming to chemist

It's too bad we can't actually go to Titan and look for life there, but as we all know, this is well outside the purpose of the space program.

The space program exists to establish manned bases on the moon and Mars, so that when life on Earth is extinguished, as it likely will be within the next few hundred years, humanity can live on in little domes, desperately clinging to life for as long as possible.

We simply don't have the resources to accomplish this, while at the same time sending robotic missions to places like Titan.

yoohoo52: "...respiring with metals", don't we do that with blood?, or are they breathing out a gas with metals in it....

Respiring =/= breathing. At least not for bacteria.

Cellular respiration is the (set of)metabolic pathway(s) for producing ATP from, well, other stuff. In this case, metals.

We have plenty of resources just for some reason there are Farkers out there who would rather there are better hospitals and stuff.

Tinderlock:

And what good will your hospitals do you when all life on Earth is wiped out, as space enthusiasts will tell you is nearly an inevitability?

No, no, we need to get off this planet as quickly as possible, and that means putting everything into domes on Mars and the moon, domes with lots of people on them. As I understand it, the children of space enthusiasts will be making up a large percentage of the population of these domes.

or wars.. as Bill Hicks once so eliquently ranted, if all the world spent all its defense budget on space exploration we could all jst explore space together forever" and we wouldnt need wars because we could just move away from folk that annoyed us

brawberrys: or wars..

indeed. That tiny little bar with the 8 over it is how much the Constellation program has cost so far. The next bar is the total that it would have cost over ten years.

www.majhost.com


And if anyone would like to say that Constellation was over budget or having problem (with vibration, etc.) I challenge you to research the problems that the Saturn V development had and compare them: in other words, don't just say, "omfg 20 people died of shark attack!!" tell me percentages and comparisons: "shark attacks are up (or down) by X% but you're still more likely to die in your car on the way to the beach." Or, if you're not following me, don't tell me, "omfg Constellation was 2 billion over budget!" instead tell me, "Constellation is X% over budget, and at the same point in its development, the Saturn was Y% over budget."

And if you aren't willing to do that, then STFU.
